Application: led June 3, 1910'. .Serial N'o. 56457421 To all lLichom it may concern: Be it known that I, ARTHUR C. BADGER, of Newton, in the county of Middlesex and' l State of Massachusetts7 have invented cerfv tain new and useful Improvements in Windows, of which the following is especification. This invention relates to metal i' window frames and sashes and has for its object to` provide anovel and improved vconstruction in such frames and sashes of a character such as to enable a metal sash to be weather-tight without requiring that it' should t accurately in the channel provided frl'it inthe frame.

Hitherto ithas'been frequentlyifoundthat I" when metal window framesare setinplace' in the window openings of a buildingitsis difficult to place them with perfectl accuracy and without bendingor twisting them somewhat. This.. is particularly the case where the workmen are careless. In such a case as this, if the sashes are made to t accurately enough in the channels provided for them in the jambs of the window frame as to exclude the weather, they will bind and stick. y

It is the object of my invention to provide an attachment by which the window sash may be madeweather-tight without requiring that it fit accurately in the channel.

The manner in which I have embodied my inventionvin practical form is illustrated in the accompanying drawings` the same showing merely one possible embodiment out of many which might be employed. A y

In the drawings, Figure 1 represents a side view of a portion of the `ja1nb or-up-V right of a lwindow frame with a section ofv the side rail of a sash associated therewith l and the 'attachment forming my invention applied thereto. Fig. 2 is an elevation of* the same as seen from the right-hand side of. Fig. 1. Fig; 3 is a cross-sectional view "of the combination shown in Figs. 1 and 2. Fig. 4 is a perspective view of the same. Fig. 5 is a detail sectional view on an enlarged scale taken on line 5 5 of Fig. l. l

Referring to the drawings, the numeral 1 represents one of the sides or jambs of a metal window frame, Athe same being made of sheet metal in any of the modes of construction which have' been found practical. Parts of the sheet or sheets forming the inner wall of the frame are offset to form the inner bead 2, the outer bead 3 and the parting bead LLbetween the sashes of the -Patented May 9, 1911.4 l

window. These beads form the usual channels 5 and 6 in which the sashes run. In the drawings the uprightv side A'rails of the bottom sash 7 and topsash 8 are'shown as occupying these' channels respectively.

.Up to theprcsent time the most commonly employed method of making vthe sashes of a -sheet metal window frame weatheretight has been to make the rails thereof suiiciently large to-it'closely in the guiding channels It frequently happens, how- Aof the frame. ever, that owing tocareless work or other `cause, the upright members of the window frames are not setA 1n the window openings with absolute accuracy, but onthe contrary are somewhat bent or twisted. The result is that accurately fitting sashes do not run in their channels easily, butbind so'much as to make their operation difficult or impossible.

It has been my object to overcome this difculty` and accordingly I construct the sashes of sufficiently less width than the channels in the frame to permit them to run easily,

even though the frame may be bent Vor twisted considerably out of line when being set. This feature will be observed from Fig. 3, wherein it appears that the sash .rails are of considerably less width than the channels 5 and 6 and that considerable clearanceis left between them and the parting bead 4..

all circumstances. In Vorder, however, to make vthe sash water-tight, I provide each side rail of each sash with means adapted to overlap one of the beads'and adjustable to v'fit closely enough upon-such beadto exclude lso The clearance is intended to be great enough I to permit free movement of the sashes-under thereto, preferably adj'ustably, f by any desired means', such, for instance,aas screws 10 passing through the strip vand into the window sash. lConveniently the sheet metal wall of the-sash .rail is thickened and.

strengthened suiiciently to take the -threads of the screws by means of reinforcing stripsA I 11, ri-veted to the rail at the points where the screws are located, while washers 12 are placed between the head of each bolt and the weather strip. Preferably the strip is viously slotted where-the screws pass through as shown at 10l order .that the offset portion of the strip may be adjusted toward or from the edge of they bead.

-From an inspectionof Figs.-3 and it will be noted that the offset or transverse part of the strip is longer than' the thick- 9b is bent back toward ness of the beadand that the edge of the web the edge of the weather. strip` to make close contact with the bead, while at the same time permittigfit to yield 'in case the frame should not be properly inline. As prestated" the upright .rails in both sashes are preferably p provided with such Weather '-stripshaving .substantially thecharacteristics'described. These stri s are so arranged on the sashes that 'they will not interfere with eachother when'the sashes are Strips' are adjacent beads, and they tightened sulic'iently-to cause the edges of raised and lowered, hence 'thestrip carried by the 'lower sash is on'ithe inner wall thereof narrower than the channels provided toreceive them, that they will run'` freely, no f matter howy much tort'e'd, that is,

the frame may be diswlthin the limits permitted in dotted lines in Fig. 1, sueh slots extending transversely of its length, in

the bead. This allows as possible,.without unduly i111-,k

by building practice, provided only that the stripsaresadjusted as to prevent binding.

lof

By means of the construction and-mode `use hereinbefore described, it is possible to make vany sheet metal window weatherltight, without at the same time necessitating such extremely careful workin setting the windowfframe into a` building as toavoid any twisting or warping thereof whatever.

I claim, 1. The'combination of a sheet metal windowframe having grooves, and sashes ar ranged to run in such grooves, the sashes being of less width than the grooves, and independently adjustable means carried by a fsash and engaglng a bead of the frame for 'Amakingthe sash Weather-tight.

2. rI he combination of a-wihdow frame having .sash-guiding channels, sashes arranged to travel in such channels and being sufficiently narrow to move easily in the same when the frame is so distorted as to' destroy the alinement of the grooves, and adjustable means carried by a sash and embracing one of the beads of the frame for excluding the weather.

3. In a sheet metal Window the combinatlon ofa frame having beads forming sash- 'guiding channels, sashes in said channels,

and a strip adjustably secured upon each of said sashes',

mote from the s'ash.

In testimony whereof I have affixed my signature in presence of two witnesses.
